GSM SIM800L TTL WITH ANTENNA













Features:
  • 2G quad-band @ 850/900/1800/1900 MHz
  • Receive and make calls using the speaker and microphone outputs
  • Receive and send SMS
  • Connect to the Internet via GPRS
  • Listen to FM radio broadcasts
  • Accepts AT Commands
  • SIM800L is designed with power saving technique so that the current consumption is as low as 0.7mA in sleep mode.

Specifications:
  • Power supply: 3.4V ~4.4V
  • Power saving: typical power consumption in sleep mode is 0.7mA (AT+CFUN=0 )
  • Frequency bands:  Quad-band: GSM 850, EGSM 900, DCS 1800, PCS 1900. SIM800L can search the 4 frequency bands automatically. The frequency bands can also be set by AT command “AT+CBAND”. Compliant to GSM Phase 2/2+
  • Transmitting power: Class 4 (2W) at GSM 850 and EGSM 900; Class 1 (1W) at DCS 1800 and PCS 1900
  • GPRS connectivity: GPRS multi-slot class 12 (default); GPRS multi-slot class 1~12 (option)
  • Data GPRS: GPRS data downlink transfer: max. 85.6 kbps; GPRS data uplink transfer: max. 85.6 kbps; Coding scheme: CS-1, CS-2, CS-3 and CS-4; PAP protocol for PPP connect; Integrate the TCP/IP protocol. Support Packet Broadcast Control Channel (PBCCH); CSD transmission rates: 2.4, 4.8, 9.6, 14.4 kbps
  • CSD: Support CSD transmission
  • USSD:Unstructured Supplementary Services Data (USSD) support
  • SMS: MT, MO, CB, Text and PDU mode
  • SMS storage: SIM card
  • SIM interface: Support SIM card: 1.8V, 3V
  • External antenna: Antenna pad
  • Audio features: Speech codec modes: Half Rate (ETS 06.20); Full Rate (ETS 06.10); Enhanced Full Rate (ETS 06.50 / 06.60 / 06.80); Adaptive multi rate (AMR); Echo Cancellation; Noise Suppression
  • Serial port and debug port: Serial port: Full modem interface with status and control lines, unbalanced, asynchronous; 1200bps to 115200bps; Can be used for AT commands or data stream; Support RTS/CTS hardware handshake and software ON/OFF flow control; Multiplex ability according to GSM 07.10 Multiplexer Protocol; Autobauding supports baud rate from 1200 bps to 57600bps; upgrading firmware. Debug port: USB_DM and USB_DP. Can be used for debugging and upgrading firmware.
  • Phonebook management: Support phonebook types: SM, FD, LD, RC, ON, MC.
  • SIM application toolkit: GSM 11.14 Release 99
  • Real time clock: Support RTC
  • Timing functions: Use AT command set



  • Operating modes:
Normal operating modes
  • GSM/GPRS SLEEP. Module will automatically go into sleep mode if the conditions of sleep mode are enabling and there is no on air and no hardware interrupt (such as GPIO interrupt or data on serial port). In this case, the current consumption of module will reduce to the minimal level. In sleep mode, the module can still receive paging message and SMS.
  • GSM IDLE. Software is active. Module is registered to the GSM network, and the module is ready to communicate.
  • GSM TALK. Connection between two subscribers is in progress. In this case, the power consumption depends on network settings such as DTX off/on, FR/EFR/HR, hopping sequences, antenna.
  • GPRS STANDBY. Module is ready for GPRS data transfer, but no data is currently sent or received. In this case, power consumption depends on network settings and GPRS configuration.
  • GPRS DATA. There is GPRS data transfer (PPP or TCP or UDP) in progress. In this case, power consumption is related with network settings (e.g. power control level); uplink/downlink data rates and GPRS configuration (e.g. used multi-slot settings)
Power down mode
Normal power down by sending AT command “AT+CPOWD=1” or using the PWRKEY. The power management unit shuts down the power supply for the baseband part of the module, and only the power supply for the RTC is remained. Software is not active. The serial port is not accessible. Power supply (connected to VBAT) remains applied.
Minimum functionality mode
AT command “AT+CFUN” can be used to set the module to a minimum functionality mode without removing the power supply. In this mode, the RF part of the module will not work or the SIM card will not be accessible, or both RF part and SIM card will be closed, and the serial port is still accessible. The power consumption in this mode is lower than normal mode.

This board draws a maximum of 2 A with an input voltage of 3.7 V to 4.2 V. This means you must not connect its pins directly to a 5 V Arduino! It doesn't even run on 3.3 V. The solution is either to use a voltage regulator or just have the SIM800L draw from a 3.7V Li-Po battery.
